Nav Menus: Fix a PHP 7.3 error when switching themes. 

When switching themes, `wp_map_nav_menu_locations()` is used to ensure nav menus are placed in the relevant menu location. Occasionally, menus are registered to locations with numeric slugs, rather than strings. `wp_map_nav_menu_locations()` assumed it would be the latter, and ran `stripos()` on those numeric slugs. This behaviour is deprecated in PHP 7.3.

As this is the last known PHP 7.3 incompatibility, this commit also removes PHP 7.3 from Travis' `allowed_failures` list.

Props desrosj, jorbin.
See #45018.
